I love using these capsules to help me fall asleep. I have noticed they are best when used infrequently. I alternate these with Gabba, magnesium and others...

I just started taking this along with Thrive GABA to supplement my melatonin. I have struggled with insomnia even as a child (now am 62). I'm not saying there's any magic here but I have been sleeping sounder. And I love that it's an affordable supplement.
